Psittacosis - Overview

Alternative Names

Ornithosis; Chlamydia psittaci

Definition of Psittacosis:

Psittacosis is an infection caused by Chlamydia psittaci, a type of bacteria found in the droppings of birds. Birds spread the infection to humans.

Causes, incidence, and risk factors:

Psittacosis is a rare disease: 100 - 200 cases are reported each year in the United States.

Bird owners, pet shop employees, persons who work in poultry processing plants, and veterinarians are at increased risk for this infection. Typical birds involved are parrots, parakeets, and budgerigars, although other birds have also caused the disease.
